BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to compositions containing paramethoxycinnamaldehyde, hereinafter referred to as PMCA, as a flavoring agent and sweetener. PMCA can be used to impart a desirable flavor and sweetness to a variety of oral, labial and ingestible comtended to be added to a variety of oral, labial and in-- gestible compositions to impart sweetness and flavor thereto. The present invention still further relates to a method of imparting sweetness and flavor to oral, labia] .or ingestible compositions, with or without the use of other flavorants and/or sweeteners. Y

2. The Prior Art In recent years, there has been considerable activity aimed toward the production of artificial sweetening and'flavoring agents for use by persons affected by physiological disorders such as diabetes mellitus and by those who must restrict their caloric intake as part of a weight control regimen. Such artificial sweeteners and flavoring agents are useful not only in foods and beverages but are'also useful in certain oral and cosmetic compostions. Examples of such compositions include lipsticks, lip pomades, dentifrices, mouthwashes, mouthsprays and the like. Such artificial sweeteners and flavorants are advantageous in oral compositions as they are non-cariogenic, ie they do not contribute to dental caries. This non-cariogenicity apparently results because these artificial sweeteners and flavorants are not metabolized in the mouth by oral bacteria to form acids which are the primary cause of dental caries.

Hertofore, sweetness and flavoring characteristics have been imparted to the compositions described .above by the use of various synthetic sweetenersand .flavorants. The most commonly used artificial sweeteners have been the cyclamates, which have come under governmental restriction and are no longer commonly used, and the saccharin compounds. Although the sac- 'charin compounds possess sweetness characteristics, they are undesirable as the sole sweetening agent in most food and beverage compositions because of the lingering bitter aftertaste perceived by most users.

While saccharin and the cyclamates have been in common use for a numer of years, more recently a se- :ries of new artificial sweeteners which can be broadly classified as dihydrochalcones have been discovered. For example, Horowitz and Gentili, US. Pat. No. 3,087,821, teach the use of various dihydrochalcones having sugar substituents (glyconic dihydrochalcones) as sweetening agents. The application of Rizzi, entitled Dihydrochalcone Sweetening Agents, Ser. 'No.

76,972, filed Sept. 30, 1970, now U.S. Pat. No. 3.739,064,'discloses the useof certain aglyconic dihydrochalcories as sweetening agents. Another recently discovered synthetic sweetener, 6-(trifluoromethyl)- tryptophane, isdi'sclosed by Kornfeld in U.Sl Pat. No. 3,535,336 which issued on Oct. 20, 1970. And still another recently discovered synthetic sweetener, 5-(3- hydroxyphenoxy)-lH-tetrazole, is disclosed in U.S. PatjNo. 3,515,727, June 2, 1970, to Garbrecht.

Paramethoxycinnamaldehyde is not a new compound and is known in the art. See, for example, Arctander,

Perfume and Flavor Chemicals, Vol II, No. 1869. PMCA occurs naturally in several essential oils such as basil and estragon. However, the art does not teach or suggest either the sweetening and flavoring characteristics of PMCA or the compositions of the present invention.

Accordingly, it is a primary object of the present invention to provide a variety of oral, labial and ingestible compositions having desirable sweetness and flavor characteristics.

It is another primary object of the present invention to provide sweetening and flavoring compositions, or concentrates.

It is still another object of the present invention to provide low calorie, relatively non-cariogenic food and;

beverage compositions.

It is yet another object of the present invention" to" provide improved oral, labial and ingestible compositions containing PMCA and, in addition, commonly known sweeteners and/or flavorants.

It has been surprisingly found that compositions which contain from about 0.0001 to about 2.0 percent of PMCA possess highly desirable sweetness and flavor characteristics with or without the addition of other sweeteners and/or flavorants. Compositions of the present invention embody a variety of oral, labial and ingestible compositions containing PMCA suitable for use in their intended form. The compositions of the present invention may be embodied in a variety of dry as well as liquid concentrates containing from about positions, PMCA may be added alone, or as one of the concentrated compositions which are more fully discussed hereinafter.

It has also been found that when PMCA is mixed or codissolved with commonly known sweeteners, the result is a composition possessing enhanced sweetness characteristics.

In addition, it has been found that when PMCA is mixed or codissolved with or in commonly known flavorants, the result is an enhanced flavor.

The present invention also relates to a method of imparting flavor and sweetness to oral, labial and ingestible compositions and the like by adding to said compositions PMCA or'concentrated compositions containing PMCA in the proper amounts.

The term labial as used herein refers to all compositions which in the ordinary course of usage come into contact with the lips. Such compositions include, for exampleflipsticks and lip pomades. The term oral compositions as used herein refers to all compositions which in their ordinary course of usage come into contact with the surfaces of the oral cavity, and include compositions for use in the oral cavity, and those that are inhaled through the oral cavity. The term ingestible compositions includes food and beverages and the like.

Such compositions include a variety of beverages, foodstuffs, dentifrices, mouthwashes and mouthsprays, chewing gums, and confections, including medicated confections such as cough drops, cough syrups and lozenges, as well as other pharmaceutical preparations. Such compositions are also meant to include smoking tobaccos which, when burned, produce smoke" which is inhaled into the oral cavity.

Non-limiting examples of foodstuffs that may be sweetened and flavored by the compositions of the present invention include: cakes, pies, breads, rolls, cereals, cookies, candies, frostings, gelatin, tea, and coffee, prepared fruits such as apples, peaches, pears, cherries, and strawberries, prepared vegetables such as sweet potatos, beets, pickles, and tomatoes, sauces, and the like, wherein a sweetened and enhanced flavor are desired.

DETAILED DESCRIPTION OF THE INVENTION More specifically, the present invention relates to compositions which contain from about 0.0001 to about 20.0 percent by weight of paramethoxycinnamaldehyde, hereinafter referred to as PMCA and as a flavoring agent and sweetener.

PMCA has the structural formula:

CH=CHCHO o-cn PMCA may be made by well-known processes such as that disclosed in British Pat. No. 1,291,246 to Montgomery, October 4, I972. The PMCA product may contain impurities but a more pure product can be obtained by the process of recrystallizing.

Preferred compositions of the present invention are oral, labial and ingestible compositions as defined above containing PMCA in amounts of from about 0.0001 to about 2.0 percent. Amounts of from about 0.0002 to about 1.0 percent are even more preferred, with amounts of from about 0.0005 to about 0.3 percent being most preferred. Such compositions can contain PMCA alone or in combination with other sweeteners and/or flavorants hereinafter described.

Combinations of Paramethoxycinnamaldehyde and Other Sweeteners As discussed briefly heretofore, it has been discovcred that when PMCA is mixed or codissolved with other known natural orsynthetic sweetening agents, the resulting composition has enhanced sweetness characteristics. I

Examples of such other suitable known synthetic sweetening agents include: saccharin, 6- (trifluoromethyl) tryptophane, -(3-hydroxyphenoxy)- lH-tetrazole, and certain aglyconic dihydrochalcones as defined in detail in the application of George P. Rizzi entitled Dihydrochalcone Sweetening Agents, Ser.

No. 76,792, filed Sept. 30, 1970, wherein small amounts of hesperetin dihydrochalcone and certain homologs thereof are used to provide novel sweetening compositions useful in various edible products.

PMCA may also be combined with other sweetening agents which may be naturally occurring or prepared from natural compounds. Examples include: sucrose, lactose, dextrose, levulose, maltose and the like.

Most preferred for this aspect of the invention is PMCA admixed or codissolved with an aglyconic dihydrochalcone, perferably hesperetin dihydrochalcone. Such a composition possesses desirable enhanced flavor and sweetness characteristics.

Combinations of Paramethoxycinnamaldehyde And Other Flavorants It has also been discovered that compositions containing PMCA mixed or codissolved with other known flavorants results in a flavoring agent having enhanced flavor. Broadly, such flavorants include liquid and powdered extracts. Examples of such extracts include: oil of sweet birch, oil of Spearmint, oil of Wintergreen, anise oil, dill oil, celery seed oil, various citrus oils including lemon, orange, lime, tangerine and grapefruit oils, clove oil, peppermint oil, cassia, carrot seed oil, cola concentrate, ginger oil, angelica oil, vanillin and the like, singly and in admixtures. These flavors are obtained from the appropriate plant sources by extraction in' the manner well known to those skilled in the art or may be synthetically made by known methods. Depending on the flavorant employed, an additional solvent may be employed to obtain the desired solution.

Solvents When it is desired to have a liquid composition containing PMCA, it is important to utilize a suitable ingestible solvent in which to dissolve and/or suspend the PMCA to form the desired flavor and sweetening composition. It is equally as important to employ a suitable solvent to codissolve and/or suspend the PMCA and other sweetening and/or flavoring agent which may additionally be used.

The PMCA employed herein is slightly soluble in water, but more soluble in various polar, organic liquids. It is, therefore, possible to provide organic solvents and organic-aqueous solvents in proper formulations to dissolve PMCA alone, or to codissolve PMCA with other sweetening agents and/or flavorants, thereby providing desirable sweetening and flavor compositions for use in a variety of oral and labial compositions.

The solvents suitable for solubilizing the PMCA and other combinations containing PMCA herein described are any of the polar, organic liquids and water containing said polar, organic liquids in the amounts hereinafter detailed. Of course, when it is desired to prepare artificial sweeteners suitable for prolonged or repeated ingestion by humans, it is necessary to use as a solvent for the PMCA a polar, organic liquid which is toxicologically acceptable. The hereinafter noted classes of polar, organic liquids which can be used to solubilize PMCA, PMCA/sweetener and/or PMCA/flavorant combinations can all be ingested to a greater of lesser extent by humans without ill effects. For example,

many of the organic acids are found in oxidized fat mix-- tures and acetic acid is a well-known constituent of vinegar. As hereinafter noted, organic acid esters and major components of most naturally occurring flavor oils. Mercaptans are found in vegetables such as the onion and garlic, while a variety of polar, organic liquids are known to be present in the so-called fusel oil component of alcoholic beverages. Many of these polar, organic liquids cause no ill effects if ingested occasionally and in low concentrations, but some should be avoided if repeated use is anticipated. Accordingly, there are certain preferred polar, organic liquids which can be employed herein singly, in combination one with another and/or with water to provide desirable flavoring and sweetening compositions. These preferred, polar, liquid, organic compounds are sometimes hereinafter referred to as ingestible organic solvents. Preferred, ingestible, polar, organic liquid solvents suitable for use herein, singly, in admixtures and with water for the preparation of artificial sweetening compositions .containing PMCA and other PMCA combinations dis- .closed herein include the ingestible members of the hereinafter disclosed classes of polar, organic liquids, :especially those detailed in the list of permitted food additives periodically prepared and issued by the United States Food & Drug Administration and published in the Federal Register, andv commonly referred to as the GRAS (Generally Recognized As Safe) list, which is incorporated herein by reference.

Another group of ingestible organic solvents useful herein are the polar, organic liquids classified as safe for limited use in foods under the provisions of regulation 121.1164 of the US. Food and Drug Administration. A wide variety of ingestible polar, organic liquids are in this category. For example, certain liquid alcohols and glycols, low molecular weight organic acids (i.e., C C organic acid esters, aldehydes, and ketones, aromatic as well as aliphatic and mixtures thereof, serve to solubilize the PMCA and other combinations disclosed herein and can be used herein, either alone or in mixtures. Ketones such as acetophenone, 3-decen-2-one, isopulegone and the like, all dissolve PMCA combinations used herein, to provide artificial sweetening compositions. Aldehydes such as benzaldehyde, decanal, and the like, are similarly useful herein. A variety of alcohols can also be used to dissolve the compositions used in the practice of this invention to form artificial flavoring and sweetening compositions. Ethyl alcohol, l-propanol, 3-hexen-l-ol, neopentyl alcohol, l-decanol, sorbitan monooleate polyoxyethylene and the like, are all suitable for use singly, in admixture one with another, and in water, to provide artificial flavoring and sweetening compositions.

The liquid organic esters of the formula R"COOR, wherein R" represents straight-chain and branched alkyl groups having 1 to carbon atoms, are a pre- ;ferred class of solvents for use herein. The usefulness of such esters arises both because of their good solvent 'properties and by virtue of the fact that many esters are suitable for prolonged ingestion, themselves being .major components of most natural flavor oils. Nonlimiting examples of esters useful as ingestible polar, .organic liquid solvents herein include: pentyl pentano- ,ate, isobutyl formate, ethyl acetate, amyl valerate, isolamyl valerate, butyl butyrate, isobutyl propionate, iso- ;amyl decanoate, ethyl propionate, ethyl butyrate, isogamyl acetate and isobutyl valerate all of which are suitable for use singly, in admixtures, and with water, in the instant invention.

Similarly, various naturally-occurring and synthetically-reconstituted flavor oils are suitably employed to solubilize the PMCA and combinations thereof with other flavoring and sweetening agents disclosed heretofore. It is not possible to specify with certainty the compositions of these various oils other than that they are highly complex liquid mixtures containing polar compounds such as lactones, alcohols, ketones, aldehydes, thiols, acids and acid esters. Some flavor oils contain nitriles, imides, organonitrates and the like. A long history of use by humans has shown that such flavor oils are physiologically acceptable and they are thus also preferred for use as ingestible organic solvents herein. Often, such flavor oils are employed with ethyl alcohol and propylene glycol to provide extracts, tinctures and concentrates containing said oils, and it is a contemplated mode of the practice of this invention that such solutions can be used to solubilize the combinations employed herein so as to provide flavoring and sweetening compositions. These naturally-occurring, ingestible organic solvent oils can also be used with water and any of the above-noted liquidsas a cosolvent. Non-limiting examples of flavor oils suitable for employment as solubilizing agents for PMCA and combinations thereof include: oil of sweet birch, oil of spearmint, oil of Wintergreen, anise oil, dill oil, celery seed oil, various citrus oils including lemon, orange, lime, tangerine and grapefruit oils, clover oil, peppermint oil, cassia, carrot seed oil, cola concentrate, ginger oil, angelica oil and the like, singly and in admix: tures, and all such oils can be used in the practice of this invention. These oils are obtained from the appropriate plant sources by extraction in the manner well known to those skilled in the art. 7

As discussed above, any of the above polar organic solvents in which PMCA and combinations with other flavoring and/or sweetening agents heretofore disclosed are soluble can be further diluted in water to yield desirable sweetening and flavoring compositions.

For example, PMCA can be dissolved in ethyl alcohol and then diluted with an appropriate amount of water to yield the desired concentration of PMCA, which composition is suitable for flavoring and sweetening foods and beverages. in like fashion, ethyl acetate can be used to dissolve PMCA and hesperetin dihydrochalcone and can be subsequently diluted with water to yield a sweetening and flavor composition in a desired concentration. Alternatively, PMCA or combinations thereof disclosed herein can be dissolved in pure ethyl alcohol in a desired concentration and the solution employed as a flavoring and sweetening composition. Thus, it is seen that dissolution of the PMCA and previously disclosed combinations thereof in polar, organic liquids, in mixtures thereof, and in mixtures thereof and water, results in solutions suitable for use as artificial flavoring and sweetening agents.

As hereinbefore noted, many of the ingestible polar, organic liquids which can be used to solubilize PMCA and the other preferred combinations of the present invention, especially the esters, have flavor properties of their own and are recognized as being major constituents in many natural flavor oils. Thus, when such solvents are used herein, even at low concentration, they will impart to the composition being sweetened some of their own flavor; this is sometimes desirable. However, when it is desired to prepare artificial sweetening compositions containing PMCA having essentially no flavor sensation other than that provided by the PMCA, it is necessary to employ as the ingestible organic solvent for said combinations :1 material having little, or no, flavor properties of its own. Two ingestible organic solvents which fulfill these requirements are ethyl alcohol and 1,2-dihydroxypropane, and these solvents are preferred for use herein when it is desired to prepare artificial sweetening compositions having no additional flavor properties other than those possessed by PMCA. Of course, such sweetening compositions prepared with ethyl alcohol or 1,2-dihydroxypropane can be flavored by the addition of flavor oils, if so desired.

The useful concentration of 1,2-dihydroxypropane in the sweetening compositions containing PMCA is limited by the astringency of this compound. For this reason, sweetening compositions containing this solvent should contain no more than about 3% of the 1,2-dihydroxypropane, the remainder of the solvent being water or ethyl alcohol. Alternatively, more concentrated solutions of 1,2-dihydroxypropane, or the compound itself, can be used in the preparation of concentrated sweetening compositions which, in use, are diluted so that the amount of 1,2-dihydroxypropane in the sweetened food is below the astringency level.

Especially preferred ingestible solvents used herein are ethyl alcohol, orange oil, tangerine oil, lemon oil, lime oil, grapefruit oil, spearmint oil, peppermint oil, clove oil, 1,2-dihydroxypropane, acetic acid, isoamyl acetate, isoamyl valerate, butyl butyrate, isobutyl propionate, and sorbitan monooleate polyoxyethylene (20), both singly, in combination, and in combination with water.

When ethyl alcohol is selected as the ingestible polar, organic liquid solvent for use in this invention, it can be used singly and in various proportions with water. Solutions of the PMCA or the other preferred compositions disclosed herein of the concentrations hereinbefore disclosed in pure ethanol, and in ethanol-water mixtures containing from about 0.15 to 99% ethanol, are all suitable for use as sweetening and flavor compositions. 1

Formation of Solvent Containing Liquid Concentrates Another aspect of the present invention is a variety of concentrated liquid compositions, which when added to the desired oral or labial composition, is diluted to provide said oral or labial composition with the appropriate amount of PMCA. Said concentrates can contain PMCA alone, or in combinations heretofore discussed with other flavorants and/or sweeteners. In such concentrates, PMCA can be present in amounts of from about 0.0001 to about 20.0 percent, preferably from about 0.01 to about percent, most preferably from about 0. 10 to about 5.0 percent.

Such concentrated solutions and concentrates of PMCA and other combinations thereof (i.e., PMCA/- sweetener and/or flavorant) can be accomplished by simple admixture with any of the appropriate ingestible polar, organic liquids. Gentle warming can be employed to speed the rate of solution but this is entirely optional, as the PMCA and combinations thereof-of the present invention are found to be relatively soluble in the above noted ingestible organic solvents. When heating is employed, temperatures of from 40C to 90C are suitable. Preparation of aqueous-organic solutions of PMCA and PMCA/sweetener and/or flavorant combinations can be accomplished either by dissolving the PMCA or combination thereof in the desired ingestible polar, organic liquid and admixing the resulting solution with water, or by simply adding the PMCA or combination thereof to a mixture of water andingestible organic solvent. Both of these methods are suitably employed in the practice of this invention, but it is usually found to be quicker to dissolve the PMCA or combination thereof in the ingestible polar, organic liquid and then to admix the resulting solution with water. The amount of organic solvent required to dissolve the PMCA and combinations thereof employed herein is not critical since any of the above-named solvents will dissolve sufficient material to provide concentrations falling within the ranges disclosed heretofore. Gener-. ally, ratios of ingestible organic solvent to PMCA of about 25:1, and greater, are suitable. When aqueousorganic solvent systems are employed to dissolve PMCA or combinations thereof, the total concentration of ingestible polar, organic liquid needed to insure solubility of PMCA or combinations thereof in the water depends to some extent on the amount of PMCA and other compounds to be dissolved.

Dry Concentrated Compositions Containing PMCA Still another composition of the present invention embodies dry concentrated compositions wherein PMCA is admixed with a non-toxic, ingestible diluent. In such concentrated compositions, PMCA is present in amounts of from 0.0001 to about 20 percent, prefer ably 0.01 to about 10 percent, most preferably from about 0.10 to about 5.0 percent. It is to be recognized that in such a dry or liquid concentrate as previously,

discussed, PMCA can be present in amounts greater than 20 percent. Practicality in terms of economics and product desirability were the criteria used in arriving at said upper limit. In the practice of this aspect of the invention, any of the commonly known diluents may be used. Non-limiting examples of such diluents include: dry starch, powdered sucrose, lactose, kaolin, mannitol, dicalcium lactate, magnesium carbonate, magnesium oxide, calcium phosphate, powdered glycyrrhiza, or other commonly used diluents. Such dry compositions can then be used to enhance the flavor of and sweeten oral and labial compositions and the like by addition thereto in amounts to achieve a flavor and sweetness desirable to the user.

Oral, Labial and ingestible Compositions Containing l-TMCA Finally, the present invention provides for imparting to or enhancing the sweetness and flavor of oral compositions such as dentifrices, mouthwashes, mouthsprays, labial compositions such as lipsticks and lip pomades, and ingestible compositions such as foodstuffs and beverages, and the like. The oral, labial and ingestible compositions of the present invention contain a concentration of PMCA of from about 0.0001 to about 2.0 percent, preferably from about 0.0002 to about 1.0 percent, most preferably in an amount of from about 0.0005 to about 0.3 percent by weight of the composition.

Dentifrices typically contain an abrasive polishing material, sudsing agents, flavor and sweetening agents. Toothpastes usually additionally contain humectants and binders.

Any abrasive polishing material which does not excessively abrade dentin can be used in dentifrice com-.

positions. These include, for example, calcium carbonate, dicalcium orthophosphatedihydra'te, calcium pyro phosphate, tricalcium phosphate, calcium polymeta phosphate, insoluble sodium polymetaphosphate,' and' resinous abrasive materials such as particulate condensation products of urea and formaldehyde, and others such as disclosed by Cooleyet al. in US. Pat. No. 3 ,070,510 granted Dec. 25 1962. Silica xerogel's as disclosed in US. Pat. No. 3,538 ,230ito Pader et alion Nov. 3, 1970 can also be used in the compositions of the present invention.

The total amount of abrasive materials in the dentifrice embodiments of the present invention can range from 0.5 to 95 percent by weight of the dentifrice. (All percentages specified hereinafter refer to 'weight percent of the total composition unless otherwise spe'ci fled.) Preferably, toothpastes contain from to 60 percent, and tooth powders contain from 6 to 95 percent.

Dentifrices usually contain sudsing agents in an amount of from about 0.5 to about 5.0 percent. Suitable sudsing agents for use in the dentifrices of this in- 1 vention are those which'yield substantial levels of foam and which are otherwise acceptable for use in 'the oral cavity. Examples of suitable sudsing agents include the water-soluble salts of alkyl sulfate having from 10 to l 8 carbon atoms, such as sodium lauryl sulfate; water soluble salts of sulfonated monoglyceri'des, such as sodium coconut monoglyceride sulfonate; water-soluble salts of fatty acid amides of taurine, e,g'., sodium' N-methyl-N-palmitoyl tauride; water-soluble salts' of fatty acid esters of isethionic acid, e.g., the coconut acid ester of sodium isethionate; and substantially satu' rated aliphatic acyl amides of saturated aliphatic monoamino carboxylic acids having 21 to.6' carbon atoms and in which the acyl radical co nt ains llto 16 carbon atoms, e.g., sodium N-lauroyl sarcosinate. Mixtures of two or more sudsing agents can also be used'.

One or more flavoring agents are generally employed in an amount of from about 0.01 to about 2 I0percent.

Suitable flavoring agents for use in the' dentifrices herein include, for example, PMCA, Wintergreen oil (methyl salicylate), oil of peppermint, oil of Spearmint, oil of cinnamon, oil of anise and mixtures thereof.

Sweetening agents are also generally employed in dentifrice compositions in amounts of from about 0.0]

to about 0.5 percent. Examples of suitable sweetening agents include PMCA either aloneor admixed with saccharin and/or hesperetin dihydrochalcone, and

(trifluoromethyl)tryptophane. I a

For the purposes of the present invention, PMCA is preferred as a sweetening and flavoring agent in an amount of from about 0.0002 to about 'l.0'perc ent,

preferably from about 0.0005 to about 0.3 percent.

It is to be recognized that other flavoring agents here- 'tofore disclosed in addition to PMCA may be used in amounts such that the total concentration. of ,flavoring agents is up to about 2.0 percent. Likewise, additional sweetening agents as disclosed heretofore other than .PMCA may also be used in amounts such that the total concentration of sweetening agents'is upto abo'ut0.5

percent.

In toothpastes, it is desirable to employ thickening agents such as hydroxy ethyl cellulose and watersoluble salts of cellulose ethers, including sodium carboxymethyl cellulose and sodium carboxymethyl hydroxyethyl cellulose; or natural gums, including gum karaya, gum arabic, and gum tragaca-nth. Also, colloidal magnesium aluminum silicate or finely divided silica can be used as part of the thickening agent to improve the texture of the product. Thickening agents in an amount of from '0.l"to' 5 percent can be used.

In addition to the above ingredients, toothpastes of the present' iinvention may contain oral health agents such as fluorine containing compounds. Examples of such compounds include: stannous fluoride, sodium fluoride,'lithium fluoride, indium fluoride, potassium fluoride, ammonium fluoride, sodium fluostannite, stannous chlorofluoride, sodium monofluophosphate, sodium he xafluoroantimonate and the like. Such compounds are generally present in amounts of from about 0.01 to about 1.0 percent.

It is also desirable to include some humectants or vi scosity modifying materials in toothpastes. Suitable materials for these purposes include glycerin, sorbitol, and other edible polyhydric alcohols or mixtures thereof. These materials can comprise up to 40 percent of the toothpaste composition. In addition to the aforementioned typical components of toothpaste, waterand/or ethyl alcohol can be present in toothpaste at levels up D to about percent.

Mouthwashes generally comprise a water-ethyl alco hol solution and flavoring materials such as those disclosed hereinafter. The alcohol provides an antibacte rial effect and also solubilizes the flavoring materials.

Optionally, mouthwashes also contain additional antibacterial agents such as cetyl pyridinium chloride and domiphen bromide, and humectants such as glycerin and sorbitol which give a moist feeling to the mouth. A sweetening agent can also be employed. Examples of such sweeteners are disclosed below.

Typically, mouthwashes contain 10 to ethyl alcohol, 30 to water, 5 to 20% glycerin or other humectant, 0.01 to 0.1% of an antibacterial agent, 0.05 to 0.5% sweetening agent, and 0.01 to 2.0% flavoring agent. Examples of suitable flavoring agents include PMCA Wintergreen oil (methyl salicylate), oil of pepsition is up to a total concentration of sweeteners of about 0.5 percent. 1

The aforesaid mouthwash compositions can also be administered in vaporizer or aerosol forms. When administered in aerosol forms, commonly available propellants such as hydrocarbons and fluorohalogen deriv atives, for example, dichlorotetrafluoroethane, octafluorocyclobutane, dichlorodifluoromethane and tetrafluorodichloroethane, are used. I

A typical softdrink contains carbonated water, flavoring and sweetening agents. A variety of flavoring agents are suitable for use in soft drinks. Generally, however, citrus oils are most preferred. Examples of suitable flavorants include PMCA, lemon, orange, lime, tangerine, and grapefruit oils, cola, root beer, grape, and the like. Such' fl'a'vorants are generally present in amounts of from about 0.001 to about 0.10 percent.

Examples of suitable sweetening agents include PMCA either alone or in combination with saccharin, hesperetin dihydrochalcone, sucrose, levulose, and/or 6-(trifluoromethyl) tryptophane. Sweetening agents are generally present in amounts of from about 0.001 to about 0.10 percent. PMCA is most preferred as the flavoring and sweetening agent for soft drinks in amounts of from about 0.004 to about 0.075 percent.

In addition to PMCA, additional flavorants other than PMCA such as described above can be employed to obtain a total flavorant concentration of up to about 0.10 percent. Sweeteners other than PMCA may also be used in addition thereto such that the total concentration of sweetener is an amount up to about 0.10 percent. Examples of suitable optional sweeteners have been given heretofore.

Cake mixes embodying the concept of the invention may be formulated for any of a variety of types, such as yellow, devils food, marble, spice, and so on.

Such mixes are formulated by methods commonly employed in the art. This may be conveniently illustrated by the following general ranges for yellow type cake mixes and chocolate type cake mixes, respectively, all proportions being by weight.

Yellow type cake mix:

Coloring, minor amount, if any All of the ingredients listed above may be of conventional type and quality. Thus, the flour may be the usual bleached cake flour, although a good general purpose flour can be substituted, especially if appropriate emulsifiers are provided. The ordinary granulated sugars are quite satisfactory, including sucrose, dextrose, maltose, fructose, lactose, and brown and invert sugars, alone or in combination. The ratio of sugar to flour may be adjusted as necessary for special circumstances but a ratio of sugar to flour in excess of 1:1 has long been known to result in particularly good cake mixes.

As to the shortening, any of the ordinary animal or vegetable fats, which may have been partially hydrogenated before use, is suitable. Preferably, the shortening should be of the so-called emulsified variety, containing up to 50 percent, and more normally about 5-25 percent, by weight, of one or more suitable emulsifiers. The partially esterified polyhydric compounds having surface active properties are an exceptionally valuable example of appropriate emulsifiers. This class of emulsifiers includes, among others, monoand di-glycerides of fatty acids, such as monostearin, monopalmitin, monolein, and dipalmitin; partial fatty acid esters of glycols, such as propylene glycol monostearate and monobehenate; higher fatty acid esters of sugars, such as the partial palmitic and oleic acid esters of sucrose; and phosphoric and sulfuric acid esters, such as dodecyl glyceryl ether sulfate and monostearin phosphate. Mention may also be made of the partial esters of hydroxy carboxylic acids, such as lactic, citric, and tartaric acids, with polyhydric compounds, for example, glyceryl lactopalmitate, and the polyoxyethylene ethers of fatty esters of polyhydric alcohols, such as a polyoxyethylene ether of sorbitan monostearate or distearate. Fatty acids alone or esterified with a hydroxy carboxylic acid, e.g., stearyl-Z-lactylate, are also useful. The condition of the shortening may vary from distinctly liquid to very firm. We have found that slightly better results are achieved with normally solid shortening and, in this case, dissemination throughout the dry ingredients is facilitated by melting the shortening prior to mixing, as is explained more fully later. This is not to imply that liquid shortenings do not produce acceptable cakes or that solid shortenings may not be mixed except in liquid condition as any such implication would be erroneous.

The selection of a chemical leavening system from among those known in the art will pose no problem for one skilled in the formulation of culinary mixes. In general, such systems are composed of a baking soda, e.g., sodium, potassium, or ammonium bicarbonate, on the one hand, and one or more phosphate or other common baking acids on the other. Suitable baking acids include monocalcium phosphate, dicalcium phosphate, sodium acid pyrophosphate, potassium acid tartrate, monosodium phosphate, sodium aluminum phosphate, and sodium aluminum sulfate, among others. The amount of soda and the selected acid are so balanced as to achieve a pH in the resultant batter of about 6 -l0. Frequently, provision of a slight excess of soda is advantageous so as to assure absence of unreacted phosphate acid and/or to compensate for the acid tendencies of some batter ingredients.

For many mixes: it is accepted practice for the housewife to add the required amount of eggs in the course of batter preparation and this practice may be followed just as well in the present mixes. If desired, the inclusion of egg solids in the mix is an allowable alternative.

The above formulations are then processed and compounded into a mix by methods commonly used in the art, which basically comprises the following steps:

4. The minor ingredients are uniformly incorporated;

and 5. The total mixture is subjected to impact grinding to eliminate lumps from final product.

It has been surprisingly found that when PMCA alone, or as one of the other combinations described herein, is added to a cake mix as described above, in amounts of from about 0.001 to about 1.0 percent, most preferably in amounts of from about 0.01 to about 0.50 percent, that a cake prepared from such a mix possesses enhanced flavor and enhanced sweetness characteristics.

The following examples describe sweetening and flavoring compositions and their preparation as well as a variety of compositions embodying saidsweetening and flavoring compositions. Said examples are given solely for the purpose of illustration and are not to be construed as limitations of this invention, many variations of which are possible without departing from the spirit and scope thereof. Unless otherwise indicated, all per- .centages used herein are by weight.

EXAMPLE XXVI Two cakes are prepared utilizing the cake mixes of Examples XXlV and XXV. Each cake is prepared as follows:

Nineteen ounces of the cake mixes are mixed with two whole eggs and about 1 to 1 /2 cups of water. Greater or lesser amounts of cake mix and water may be used if desired. This is then mixed either by hand or with a household mixer. For hand mixing, a total of 300 strokes is used, while for machine mixing, two minutes at medium speed is adequate. After mixing, equal parts of the batter are poured into two greased 8-inch round pans and baked at 350F. for 30-35 minutes until done. The result is a devils food and a yellow cake having enhanced flavor and potentiated sweetness qualities.

EXAMPLE XXVll An instant coffee product having a sweetening and flavoring composition contained therein is prepared as follows: Five thousand pounds of roast and ground coffee 100 percent by weight through No. 8 mesh and 95 percent by weight on No. 20 mesh United States Standard screens) are used to prepare an aqueous coffee extract in a conventional countercurrent extraction train. The extraction train is composed of eight stainless steel columns connected in series for continuous operation. Each column is fifteen feet high, eight inches in diameter and holds approximately 450 pounds of the roast and ground coffee. Prior to extraction a volatile flavor fraction is distilled from the roast and ground coffee by passing 10 P510 steam through each column of fresh coffee for fifteen minutes. The volatile fraction removed from the coffee is passed into a 35F. condenser and then into a 1 10F. cold trap. The total weight of condensate obtained is 10 percent by weight of the roast and ground coffee which was steamed. The condensate is saved for addition to a liquid extract as described below.

The steam distilled roast and ground coffee is then extracted countercurrently with water. The water enters the extraction system at 300F. and is allowed to cool by natural heat losses as it passes through the system. The extract emitting from the last column has a temperature of 210F. and a concentration of coffee solubles of 22 percent by weight.

The extract is concentrated to a 50 percent soluble concentration by conventional thin-film evaporation.

Thereafter, the condensate from steamdistillation.

along with a sufficient amount of the sweetener and flavorant of Example I is added to the concentrated extract such that the final concentration of dissolved PMCA in the extract is about 0.10 percent. The extract is then spray dried in a conventional spray tower, fourteen feet in diameter and thirty-five feet in height. The extract is atomized at a pressure of 550 psig. and sprayed into a concurrent flow of hot air. The inlet temperature of the air is 560F. and the outlet temperature is 260F. The result is a coffee product which, when used as intended, possesses enhanced flavor and desirable sweetness characteristics, without the bitterness often assoeiated with such a product.
